officials from Pakistani CAA and the government regarding the safety of the Fokker F27 fleet. Employees in PIA accused the airline of being short on maintenance workers. According to the report, approximately 30 senior engineers had left the airline since January 2006. Most of them applied to Gulf-based airlines. Following negative sentiments from the public, Pakistani government ordered PIA to ground their Fokker fleet. Information Minister Muhammad Ali Durani stated that routes in the North of the country would be replaced with C-130 Hercules and other routes would be deliberated among officials for more consideration. The routes were later replaced with Boeing. All PIA Fokker aircraft were later withdrawn from service and replaced with ATR aircraft. Starting in November 2006, the Fokker F27 fleet would be replaced with seven ATR-42. In response to the grounding of the Fokker F27 fleet, fares of the routes were reportedly raised by PIA. Investigation Director General of Pakistan Civil Aviation Authority announced the formation of a board of inquiry to probe the cause of the crash, headed by Air Commodore Junaid Amin. Special investigation team assembled by PIA announced that they would compile a report within a week of the accident. The investigation would take up to three months for completion. Pakistani authorities had asked assistance from multiple foreign experts, including those from Fokker, Rolls-Royce and other air crash investigation agencies. The Pakistan Airline Pilot's Association, however, criticized the move as a "farce and an eyewash" as they accused authorities, particularly PIA, of being hesitant on involving International Federation of Air Line Pilots' Associations into the probe. They later claimed that the move was a biased attempt to put the blame on the pilots. The flight recorders were recovered from the crash site and were taken to Karachi for examination. The flight data recorder was later flown to the U.S and the cockpit voice recorder was sent to France and the United Kingdom for readout. There were concerns regarding the condition of PIA's Fokker F27 fleet. One of the relatives of the victims of the crash had told PIA authorities to ground the Fokker F27 following a flight from Islamabad to Multan. Both cockpit crew reportedly had also filed complaint in regards to the maintenance and the airworthiness of the Fokker F27 fleet. PIA, however, reiterated that their Fokker fleet was airworthy and certified for flying. Deputy Managing Director of PIA, Farooq Shah, stated
